Abstract:
The study was conducted to assess the influence of pre-harvest application of elicitors and bio-formulations (Brassinosteriod @ 0.05% and Brassinosteriod @ 0.1%, Chitosan @ 2%, Pseudomonas fluorescens @ 1x10⁸cells/ml, Bacillus subtilis @ 1x10⁸cells/ml, Salicylic acid @ 300ppm, Clove oil @ 0.2%, Eucalyptus oil @ 0.2%) on papaya fruits at different developmental stages. The first spray was taken up 2 months before harvest, 2^nd and 3^rd spray 15 days after 1^st and 2^nd spray respectively. The results revealed that treatments, Brassinosteriod @ 0.1%, Pseudomonas fluorescens @ 1x108cells/ml and Chitosan @ 2% have highly influence on biochemical parameters like total soluble solids (14.85 0B), carotene content (1.19 mg/100 g) and titratable acidity (0.23%) respectively. Their by improve the fruit quality and shelf life (ranges from 8.33 days to 9.00 days) during postharvest life of papaya cv. Red lady.
